The most recent pictures are not quite good enough to postitively ID the fish. They are a shiner species and do not look like emerald shiner to me. If they were larger individuals it might be easier to tell what they are. Young golden shiner do tend to have a greenish hue to the back area. If you take more photos try putting 2 or 3 in water in a zip loc bag. Sometimes that provides a good picture showing details of the fish. It is possible they are young common shiner.
